This invention relates to a line justifying typing machine.

An object of the invention is to provide a typing machine equipped with means whereby type written lines may be justified and delivered from y,

the machine substantially of equal length.

In producing typewritten matter from the or-4 dinary typing machine the length-of the lines is not uniform, that is they do not terminate at the same line. The present invention embodies novel means for shortening the typewritten lines which extend beyond the desired length so that when the typewritten sheet is completed the work will be delivered from the machine with the typed lines of the same desired length.

While the invention is primarily intended for the purpose above stated, in the present disclosure it is illustrated for use in connection with a variable spacing type of typing machine such as is disclosed in United States Patent No. 2,188,252 issued to applicant on January 23, 1940.

With the above and other objects in view the invention has particular relation to certain novel features of construction, operation and arrangement of parts. an example of which is given in this specification and illustrated in the accompanying drawings, wherein: l

Figure 1 shows a rear elevation of a typing machine showing the justifying attachment thereon.

Figure 2l shows a vertical sectional view taken on the line 2-2 of Figure l.

Figure 3 shows a fragmentary, plan view.

Figure 4 shows a diagrammatic view of a switch mechanism employed,

Figure 5 shows a fragmentary, side elevation', and

Figure 6 shows an enlarged, fragmentary, side elevation of an arcuate toothed segment employed.

Referring now more particularly to the drawings wherein like numerals of reference designate the same parts in each of the gures, the numeral I designates the frame of a typewriter, or other typing machine, of any conventional construction.

This typing machine has the transversely movable carriage 2 of the usual construction which carries the cylindrical platen 3. Attached to the carriage and located et the rear of the typing machine there is a U-shaped frame comprising the vertical side bars 4, 4 connected at their lower ends by the brake bar 5. At one side the brake bar is extended beyond the corresponding side bar 4 forming a clutch bar 6 which is also supported by the diagonal brace 6av connected at its lower end to the outer end of the clutch bar 6 and at its upper end to the corresponding side bar 4. A brake 'I is associated with the brake lbar 5 and is of the electrical magnetic type. It is electrically connected with a suitable'source of electrical energy through the wiring 9 and I0. It is pivotally mounted between the brackets 'Ia and 1b which are connected to the main frame of the typewriterl as shown in Figure 2. The brake is mounted to pivoton a horizontal axis. 'Ihe bracket Ib has an upstanding arm 1c which is provided witha laterally turned lug 1d. An adjusting screw 'le is threaded through said lug and forms a stop for limiting the range of outward movement of the brake. 'I'he brake is normally held against said stop and out of contact with the brake .bar 5 b'y means of a pull spring 8 which is connected at one end to the-upper end of the arm 'Ic andat its other end to the' brake as clearly shown in Figures 1 and, 2.

yWhen lthe brake is energized the pull of the held against movement. The electrical circuit through the wiring. 9, I0 may be completed and broken through a conventional electrical switch IId;

the rear end of the framework I there is a U- shaped guide member I2 which is closed at one end, as shown in Figure 1, and which has\.the confronting grooves I3, I3 forming guides or tracks for the spacing bar I4 whose margins are shaped to t into said grooves. 'I'his spacing bar is movable transversely, its range of movement being limited in one direction by anadjustable stop I5. A guide I6 istted between the corresponding ends of the side lbars I2a, I 2a of the guide member I2, said guide I6 being rigidly secured to the part I'I of the main frame I. The stop I5 is threaded through the part I1 and the guide I6 and has-a spur gear I8 secured on the cuter end thereof.

The spacing bar I4 has a series 0f Openings I9 therethrough, through which the dogs 20 of a erably at the outer end thereof, there is a bracket 2l and pivotably connected, at one end, to the upper end of said bracket there is a depending clutch lever 22. -The lower end of this clutch lever has the spaced upper and lower, clutch jaws 23, 23 which are spaced a sufficient.fdis-Y Secured to and extended transversely across tance apart to receivethe clutch bar 6 between them. The lower end of the clutch lever is connected to the main frame I by means of a pull spring 24. Normally this spring holds the clutch lever 22 in angular relation to the bar 6 so as to 5 cause said jaws 23, 23 to grip the upper and lower margins of the bar 6 so as to hold the said bar against movement.

The lower end`v` of the clutch lever 22 termiv nates in a depending shoulder 25"and pivoted to 10 a bracket 26, which may be suitably connected to the main frame, there is a dog 21 whose upper end is engageable with said shoulder.,A .There is, an electro-magnet 28 whose core is pivotably conneeted to the dog 21 by means of a link 2s. The 13 electro-magnet 28 is electrically connected with a suitable source of electrical energy through the wiring 30, 3| and the electrical circuit may be completed or broken through Athe electrical switch IIb. When the electro-magnet 281s energized the dog 21 will be'engaged with the shoulder andgthe clutch lever 22, will be correspondingly moved so a-sto cause the gripping surface of the-jaws 23, 23 to moveinto parallell relation with the margins of the bar 6 whereby 25- said bar will be released from the gripping action of said jaws.

Upon release of the jaws, the pull spring 33, attached at one end to the closed end of the guide member I2 and at its other end to the bar 30 I4, will cause a movement of said bar, the range of said movement being limited by one of the dogs 28 as hereinafter explained.

It may be here noted that there is a spacing dog 28 and a correspcndingspacing opening I9 in 35 the bar I1 for each type lever and one for the spacing lever:v

The numeral 34 designates a conventional key lever which is pivoted, at its inner end, to the frame and which is normally held elevated by the compression' spring 35. Corresponding with each key lever there is the conventional type bar 36 pivoted to the main frame and whose forward, or free, end is provided with the lower and upper case type 31, 38. The other end of the type b ar has the diagonal slot 39 forming a bearing for the pin 48 which extends out laterally into said slot from the upper end of the type bar link 4I which is pivoted at its lower end on the frame and has the forwardly extended arm 42 which is 50 provided with an oblong slot 43 to receive the stud 44 extending out laterally from the corresponding key lever 34. Upon depression of the key lever the upper end of the type bar link 4I will be thrown forwardly and the free end of the type bar 36 will be actuated upwardly to carry the type into printing relation with the platen 3 in the conventional manner.

'I'he inner end of each spacing dog 20 is pivotably connected to the upper end of the actuating lever 45 and the lower end of this lever is connected to the type'bar link v4I by means of the tie 46 which includes a coil spring 41. Accordingly, upon actuation of the type bar link 4I the corresponding dog 20 Iwill be projected 05 through its aligned opening I9. Upon release of the key lever 34 the spring 35 will elevate it to its original position thus releasing the tension on the spring 41 Thereupon the pull spring 48 will operate through the lever 45 to retract the corresponding dog 28. This pull spring 48 is attached at-one'end to the main frame I and at its other endtothe free end of the lever 45.

The dogs 28 operate through the openings I9 in the guide bar Il as hereinabove explained, and

the dogs 20 may be shifted vertically in said openings for a purpose to be hereinafter explained, as the shift lever 49 is manipulated to shift from lower` case to upper case letters. This shifting is accomplished in the conventional manner. The inner end of the shift lever is pivoted on the main frame inthe same manner as the key lever 44. The PVOted end of the shift lever 49 has an upstanding finger 58 whose upper end is forwardly curved and rides against the bearing face 5I of the depending arm of the bell crank 52. There are two of these bell cranks, one at each side of the machine and the free ends of whose horizontally extended arms support a transverse rod .lever 49 the finger 58 will be actuated forwardly on the track 53, and the platen support, and the platen will be elevated When the platen is in lower position the lower case letters 31 cooperate therewith and when elevated the upper case letters38 co-operate therewith in the well known manner.

The dogs 29 are mountedin a magazine ,56. This magazine has the forwardly directed brackets 51 on which the respective levers 45 are pivoted and the ends of the magazine 56 are supported on the lift levers 58, one at each side of the machine. The forward ends of the lift levers are pivoted to the framework I and these levers are connected to the horizontal arms of the bell cranks 52 by the lift lever rods 59. Accordingly, upon the actuation of the shift lever 49 the lift levers 58 and the magazine 56, with the series of dogs 20 therein, will be elevated to upper position. The dogs 28 work through suitable bearings in the magazine.

Upon actuation of a key lever 34, the corresponding type bar 36 will be operated as explained and upon operation of any type bar it 'will strike the transverse thrust bar 60. This thrust bar is supported by an upstanding guide 6I whose upper end is forwardly turned and extended through a bearing in the framework of the machine as shown in Figure 2. Extending rearwardly from the thrust bar 60 is a thrust rod 62 whose rear end is pivoted to the free end of the upstanding arm of the bell crank 63. The other arm of said bell crank has a pivoted connection with a vertically movable switch-actuating rod 64. The lower end of this rod 64 is aligned above the push rod 65 of the switch IIb.

When a type bar is actuated as above stated there attached to the upstanding arm of said bell crank and the other end of which is attached to a stationary part of the framework. Upon this actuation of the switch I Ib a circuit through the wiring 9, I8 will be completed and the electric brake 1 hereinabove referred to will be rendered active to hold the brake and clutch bars 5, 6 and the carriage of the machine stationary. 1

Upon downward movement of the rod 64 the switch IIa is also actuated to complete a circuit through vthe wiring 30, 3| and the electro-magnet 28 thus energized and the dog 21 is thus actuated against the shoulder 2,5 to release the clutch from I4 to move, under the influence ofthe spring 33,

to the left as indicated in Figure 1, and upon release of the key leverand the subsequent upward movement of/the rod 64, under the influence of the spring 66, the switch Ila will be actuated by the spring IIc to break the circuit '30, 3| and electro-magnet 29 will be de-energized and the spring 24 will th'ereupon operate to again apply the clutch to the b ar 6. 'Ihe switch IIb will f mmediately thereafter, also, break the circuit through the wiring 9, I and release the brake, allowing the carriage to move. 'I'he switches IIa, I Ib are mounted on a pivoted leverV I Ic formed of insulating material to which the rod 64 is connected and h'oused in the casing I I".

Y The numeral 61 designates a space bar leverl In the conventional vtype of typing machine there are two of these levers one on each side and connected at their forward ends by the conventional spacing bar. At an intermediate point each space bar lever is pivoted on a transverse rod 68 and upstanding from one of said levers 61 there is an arm 69. 'I'he free end of this arm is connected to the free end of the corresponding actuating lever 45 by means of a tie 1I! which includes a coil spring'll so that upon actuation of the space bar 61 the dog 20 corresponding to said bar will .leased and permitted to move only the required this automaticvariable spacing maybe accomplished, that is, the carriage is automatically respace for eachv individual letter or character as it is printed on the work. The movement ofthe carriage. that is, the spacing, takes place imme diately after the letter, or character, is imprinted on the workvv and the spacing mechanism is such that the carriage is permitted to move the exact be projected through its aligned opening I9. The

forward ends of the space bar levers 61 are normally held elevated by the coil vspring 12 which is connected at one end to one of said levers and at its otherend to the framework above. The

inner end of one of the space bar levers 61 carries an upstanding finger I3 aligned underneath the free end of the forwardly projecting arm'14 of the bell crank 63. When the space bar 61 is depressed the finger 13 will elevate the arm 14 moving the rod 64 downwardly, actuating the switch IIb as before and setting the electric brake to hold the brake bar 5 and the clutch bar 6 against movement and releasing the mechanical clutch jaws 23, 23 to permit retraction of the spacing bar I4 under the influence of the spring 33 as hereinabove explained thus controlling the spacing between the typed Words or characters. Upon release of the space bar 61 it will be elevated by the spring 'I2 thus releasing the corresponding dog actuating lever 45 and permitting the corresponding spacing dog 20 to be retracted by the corresponding ,pull spring 48.

The carriage 2 is moved by the conventional means for that purpose. As shown in Figure 1 there is an involute Ispring housedvwithin the housing 15 with its free end 16 attached to the carriage, for intermittently moving the carriage.

As also clearly illustrated, in Figure l, the openings I9 vary in width and likewise thedogs 20 which work through said openings I9 are widened laterally as shown in Figure l and for a purpose to be hereinafter explained.

The faces of various letters andcharacters used in printing and of the regular printing type vary in width over a wide range from the narrowest of lower case letters to the widest of upper case letters. However, in the ordinary typing machine the spacing for the letters and characters used is the same.' In order to adapt a typing machine, however, for use in lithography or offset printing it is necessary to provide for variable spacing, rather than the uniform spacing so that spacing for each letter, or character, will vary in accordance with the width thereof; and this should be done automatically. By the use of the space or width of the letter or character immediately after such letter or character is imprinted on the work. In order to more clearly disclose this feature the operation of the variable spacing attachment of the typing machine will be briefly stated as follows:

Upon depression of the key lever 34, the dogl l 20, corresponding to said lever will be prlected rearwardly through its opening I9, the key 'bar 36 will be actuated to cause a lower case letter 31 to come into contact with the work and print the letter or character thereon. At the same time the switch II will be actuated and the elec tric brake rendered operative to hold the brake bar 5, and the clutch bar 6, and the carriage against movement. The clutch-lever 22 will also be operated to release the clutch jaws 23, 23 from the clutch bar 6 thus releasing the spacing bar I 4' to the pull of the spring 33. The bar I4 will then move a distance' depending o n the relative width of the opening and the dog which has been projected through said opening. The relative width of said dog and opening should correspond to the width of the letter or character just impressed or printed o'n the work. Upon release of' the key lever the switches IIb, IIa will be actuated releasing the electric brake, breaking the circuit through the-wiring 30, 3| to de-energize the magnet 28 thus permitting the spring 24 to cause the clutch jaws 23, 23 to re-engage the clutch bar 6. The carriage, clutch bar 6i, and spacing bar I4 are now clutched together and can :move only a distance equal to the width of the 'letter or character last impressed on the work,

whereupon the spacing bar I4 will engage the stop I5. Each dog 20 and its corresponding opening I9 are of such relative width as to allow the carriage to move only a distance corresponding to the width of the letter or character last imprinted on the work.

When the upper case letters are to be used the shift lever 49 may be depressed thus elevating the platen and at the same time correspondingly elevating the magazine 56 so as to carrythe dogs 20 into alignment'with the widened portion of the openings 'I9 and thereupon, upon the operation of the key lever, the corresponding key bar 36 will be yactuated as hereinabove explained bringing the upper case letters, or characters, into printing relation with the work. The corresponding dog 2n will be projected through its opening I9 opposite the widened portion thereof so as to allow a greater range of movement of the spacing bar I4,.the said widened portion varying in width in accordance with the variations in width of the corresponding upper case letters. Otherwise the operation of the machine is the same as it is in the case of the lower case letters.

The line justifying attachment will now be described.

Secured to, and upstanding from theframe I,

there is an inverted U-shaped track 11 'havingthe vertical 'side bars 11a, 11a. This frame is Vertically movable in said track 'there is a plate-like carrier 19. Secured to the upper end of the frame 11 there is an electric motor 80 having a pulley 8 l xed to the shaft thereof. A nexible belt 82 has one end attached to the upper endv of the carrier 19 and its other end is wound on the pulley whereby upon rotation of the pulley in one direction the carrier will be elevated. Electrical wiring 83, 84, 84a leads to the `motor from a suitable source of electrical energy and is equipped with a manually operable switch-85 accessible to the operator.

Secured to one of the side bars 4 there is a transverse adjustable bar 86 having an elongated longitudinal slot 81 to receive the set screw 88 which is fitted through the slot 81 and is screwed into the corresponding side bars 4 and whose head clamps against the bar 86 to secure it at any selected point of adjustment. The inner end of the bar 86 has an upstanding arm -89 whose upper end is provided with a beveled guide face 90a.

There is a transverse rod 9| whose ends have bearings in the upper ends of the side bars 4, 4 as shown in Figure 1. Spaced above the rod 9| there is a transverse bar 92 preferably square in cross-section whose ends have the downwardly turned arms 93, 94 which have bearings on the rod 9| as shown in Figures 1 and 2. There is a bracket 95 which has a bearing therethrough to receive the bar 92 and which may be secured in a selected position on said bar by the set screw 96. This bracket is elongated as shown in Figure 1 and, at one end, has the upstanding supports 91, 98, the former of which carries the electric contact 99 connected with the wiring 8,4 and the latter of which carries the electrical contact |00, which is connected with the electrial wiring Upstanding from the other end of the bracket 95 there is a bearing member |02 and a standard |03. A dog |04 is pivotallymounted on the standard |03 and is normally held in engagement with a pawl |05 by means of a pull spring |06 which is longitudinal bearing face |20 arranged, under the conditions hereinafter explained, to engage the arm ||3 and release the dog |04 from the pawl |05 to cause the stopping of the motor 80 and the energizingof the electro-magnet ||2.

f The lower end of the lever I I4 has a retracted, arcuate segment |2| having a ratchet face `from end toend thereof formed with ratchet teeth |22. As shown inf` Figure 3, these teeth decrease in size toward the free end of the segment for a reason to be hereinafter stated.

There is a lever |23 which ris pivoted on the lower end of onel of the side bars 10a by means of the pin |24/ The lower end of this lever works between the adjustable stops |25, |25 carried by the bracket 1a. A link |26 is pivotally connected at one end to the dog 21 and its other end is connected, by means of the coil spring |21, to the lower end of the lever |23. Pivotally mounted on the extended upper end of the lever |23, above the pin |24, there is a dog |28 engageable with the teeth |22. This dog has a downwardly extended arm |29 which is located between an out-y wardly extended pin/|30, extending out from the lever |23, and a flat pressure spring |3| one end of which is anchored to said lever |23 and whose other end presses against the arm |20 opposite the pin |30. When the electro-magnet 28 is enerattached at one end to an arm |01 upstanding from said dog and at its other end to an anchor |08 upstanding from the bearing |02. The pawl |05 has an extended shank |09 which works through the bearings |02 and which carries a contact point ||0 engageable with either of the contact points 99 or |00. When the dog |04 is engaged with the pawl |05, the contact points 99 and I0 are in contact and when the switch 85 is closed a circuit will be vcompleted through the motor 80. When the dog |04 is released from the pawl |05, a coil push spring I, around the shank |09, will operate against a pin 90 outstandingfrom the shank |09, to move the contact point ||0 into contact with the contact point |00 and said circuit to the motor will be broken and a circuit will lbe completed through the wiring 84a and |0| through the electro-magnet l2.

The dog |04 has a depending release arm ||3 for a purpose to be hereinafter explained.

There is a lever ||4 whose upper end is pivotally mounted on the carrier 19 and is provided with an arcuate rack member ||5 which is in mesh with the corresponding arcuate rack member I6 on a cylindrical housing ||1. This housing is mounted to rotate about a central pivot pin I8 which is attached to the carrier 19. Aninvolute spring I9 is attached at one end to the pin ||8 and at its other end to thehousing ||1 and is arranged to be placed under tension as the lever I4 is moved to the right, as illustrated in Figure 1, by the corresponding turning movement of said gized, a pull is exerted through the link |26, correspondingly actuating the lower end of the lever |23 and causing the dog |28, which is in engagement with a tooth |22, to actuate the segment |2| and .lever ||4 to the right. When the electromagnet 28 is deenergized as hereinabove explained, the spring 24 will move the lever 22 to the right, the shoulder engaging the dog 21 and moving it correspondingly together with the link |26 thus allowing the lever |23 to move back to original position. 'I'he upper end of said lever, carrying the dog |28, will move in the opposite direction releasing said dog |28 from the tooth l |22 with which it is engaged and the spring |3| causing said dog to engage behind the next succeeding tooth |22. Upon release of the dog |28, the segment I2| will be held by the pawl |32 which is pivoted on the carrier 19 by means of the pin |33 and which is held' yieldingly in engagement with the teeth |22 by the pressure spring |34y which isv also anchored on said carrier. The pawl |32 has an `extended release arm |35 which is provided for a purpose to be hereinafter stated. Accordingly, while typing a line the lever ||4 will be intermittently moved to the right. As shown in Figure 1, this lever is in the position it will occupy at, or approximately at, the completion of a typewritten line before the latter has been justified. It may be here stated that by the use of the present invention as illustrated, the line willflrst be typed and the carriage then shifted and the line will be re-typed and if there determined by the position of the bracket and its appendants on the bar 92. This bracket 95 may be adjusted by loosening the set screw 96 and making the adjustment and then again tightening up said set screw. In making this adjustment the bar 86 should also be adjusted correspondingly which may be done by loosening the set screw 88 and making the adjustment and then tightening said set screw.

When the end of a line has been reached the The width of the column to be typed will be -one end to the adjacent side bar 4 and whosea 3b carriage is reversed for the .beginning of a new line. 'There is a return lever I 35 one end of which is pivotally` connected to the carriage and whose forward end has a downwardly turned grip |31. This is the usual construction now employedon conventional typing machines. a The pivoted end of the return lever |35 carries an overturned arm |38 to the free end of which one end of the push tation imparted to it by the intermediate' gear |51 so that the teeth of saidgears will be held ln close contact and there will be no lost motion betweenthem. Upon upward movement of the carrier 19 the rack member |43 will rotate the spur gear |54 and the shaft |55 and rotation wiu be imparted through the gear |50, |51 to the spur l gear I8 and the stop I5 will be screwed inwardly.

rod |39 is pivoted and the other end of this push I rod is pivotally connected to the transverse bar 92. Accordingly, when the lever |35 is actuated to return the carriage the bar 92 will be swung, on

. its arms 93, 94, rearwardly and the pin 90 projecting out from the shank |09 will strike the beveled face 90a of the upstanding ar'm 89 thus moving said shank |09 to the left so as to cause the re-engagement of the pawl |05 with the dog |04, placing the spring I I I under compression and bring the contact point I I0 into contact with the contact point 99; also the bracket 95 and its apa pendants will be swung clear of the bearing face |20 of the lever I I4 thus permitting said bracket and appendants to move with the carriage to starting position without the release arm `|I3 coming into contact withthe face |20.

The arm 94 has a depending eye |40 to whichV the upper end of the lift rod I4I is connected. 'I'he lower end of this lift rod is pivotally connected to a release lever |42' which is pivoted at other end is extended inwardly and beveled downwardly as shown ln Figure 1. When the carriage is reversed, that is, when it is moved to starting position the release lever |42 will engage underneathl the free end of the release lever |35 thus disengaging the pawl |32 from the teeth of the segment |2I and thereupon the spring ||9 will rotate the housing I|1 whichA in turn will effect the return of the lever II4 to vertical, or starting position. f

Fastened on the forward side of the carrier 1 9 there is a rack bar |43 whose forward face is pro- The distance the stop I5 is screwed inwardly will depend upon the distance the carrier 19 moves upwardly and this in turn will be determined by the time of contact of the bearing face |20 with the release arm ||3 which elects the release of the dog |04 from the pawl |05 and the stopping of the motor 80.

In use a sheet of paper will be inserted into the typewriter in the usual way and the carriage of the machine will be moved to the left, that is to starting position, and the lever I I4 will be moved, as hereinabove explained, to neutral, or vertical position. The width of the column of printed matter-will be determined by the position of the bracket 95 on the bar 92. As the carriage is moved to starting position the carrier 19 will be moved to its lower position, as shown in Figure 1, and as it is moved to its lower position the gearingIiG, |51 will rotate the gear I8to withdraw the stop I5 so that the spacing bar I4 willbe allowed its maximum range of movement. It is to be understood that the typewritten matter will be written in 'two columns. Each line as written in the rst column will be repeated in the second column. The lines of the typewritten matter in the rst column will be of variable lengths while the lines of typewritten matter repeated in the second column will be justified or of thesame, or selected length. As a line in the rst column is written the carriage will be to the left as the machine is viewed in Figure 1. As each key is struck the lever II4 will be moved a distance equal to the length of the corresponding tooth |22 with which the dog |28 is engaged sol that as the typing of vided with gear teeth |44. This rack is in'mesh Y with a spur gear which is fixed on one end of the shaft |46 mountedl in suitable bearings onthe main frame. Fixed on the other end of this shaft there is a bevel pinion |41 which is in mesh with a bevel gear wheel |48 which is xed on the shaft. |49. Fixed on this shaft |49 there is a spur gear wheel |50 which is in mesh with the transversely operating through the gearing |50, |48, |41 and |45 to move the carrier 19 downwardly to its original position.

There is also a spur gear |54 which is xed on one end of the transverse shaft |55 and which is in'mesh with the rack teeth |44. Fixed on the other end of the shaft |55 is a spur gear |56 which is in mesh with an intermediate spur gear |51 mounted to rotate on the main frame of the type- Writer and this intermediate gear is in mesh with the spur gear I8. Fastened to the outer face of the spur gear I3V there is a circular housing |58 which -contains an involute spring |59 one end of which is attached to the housing |58 and the other the line progresses, the lever II4 will be intermittently moved to the right as viewed in Figure 1. When a line in the rst column is completed the switch 85 will be closed by the operator and the motor started and the carrier 19 elevated. If the line as typewritten overruns the selected length, the release arm ||3 will have passed the upper end of the bearing face |20, the distance it mayhave moved beyond said face depending on theamount of overrun, that is the number of letters typed beyond the desired length of the line. Consequently, the amount of upward movement of the carrier 19 before the face |20 strikes the release arm |I3, and releases the dog |04, willl depend on the overrun of the typewritten line. As the carrier 19 moves upwardly the stop I5 will move inwardly to shorten up the range of move,-

ment of the spacing bar I4 and this inward movement of the stop I5 will be immediately stopped upon release of said dog |04 and the consequent stopping of the motor 80.

The teeth on the rack I2I are graduated down from right to left, as illustrated in Figure 6, by a certain mathematical progression, being coarsest or further apart at the extreme right and graduating downward to the left at that certain rate of progression required to make the angle of the face |20 an accurate gauge of the run-over divided by the number of key strokes (that is letters and spaces) required to make the line.

For example: in a line with half-inch runover beyond the length of line to `be set or typed in.its justified length, and with fifty strokes, the travel IIDWHJ nf thp 'ninth 1Q nare-vinnfrenan screw or space bar stop to a setup of .0010",

' which is the accurate space to be deducted from each stroke, or each movement of the platen to shrink the line to a length one-half inch shorter.

For a line with the same runover but with one hundred strokes, the face could only move one-half the distance of the movement in the fifty stroke line before the surface oi.' the gauge face |20 came `into contact with the pawl ||3 and cut ol the motor and stopped the movement upward of the stop l5. This would be a set up of .0005" on the space bar stop screw I5, shortening the space of each of the one hundred strokes by that much, which would be a total of one-half inch the line was shortened.

Thus the angle of the gauge lever face |20 changes with each stroke on the keyboard, and the teeth |22 on the bar |2`| being cut with mathematical precision for each stroke angle, decreasing with the proper progression so that at any given number of'strokes the angle of the gauge face |20, is always in the accurate position at the end of any typed line so that when pulled i up by the motor will contact the release arm ||3 at just the right travel to turn the space bar stop |5 to a set-up of the 4overrun, space divided by the number of strokes.

Brake means have been provided for immediately stopping the rotation of the gear I8 when themo'tor 80 is stopped so that there will be no additional movement due to the momentum of the parts. This brake means comprises a brake shoe |60 having an arcuate braking surface |6| and attached to the core of the electro-magnet ||2 there is a friction -block |62 adapted to frictionally engage the surface I6 'Upon release of the dog |04 from the pawl |05 andthe stopping of the motor 80 as hereinabove explained, the contact point ||0 will Yrnove into contact with the contact point |00 and a circuit will be completed to the electro-magnet ||2 through the wiring 84a |0| and said electro-magnet will be energized actuating the friction block into braking engagement with the friction surface |6`| and the movement of the gear I8 will be ,immediately stopped. The line will then be re-typed in the second column and the re-typed line will be 'shortened up or justified by reason of the fact that the range of movement of the spacing bar |4 has been limited so as to take up the amount of said overrun, that is, the excess length of the first typewritten line over that-desired.

The carriage is then reversed or moved to starting position, as hereinabove explained, and the next line is typed in the first column and then re'typed in the second colunmas before. Said re-typed lines being justified in the manner stated.

What I claim is:

1. A typing machine comprising a frame, a Work holding carriage movable on the frame, a plurality of printing type of varying widths, means for selectively actuating the type into printing relation with the work on the carriage to form a printed line, a movable spacing bar, a clutch for connecting the movable spacing bar with the carriage, a clutch on the frame operable to hold the carriage against movement, means for controlling the range of movement of the spacing bar, means arranged to be rendered operative by the operation of the line printing mechanism and under the control of the operator and efed in accordance with the overrun of the printed. line and the number of characters in the line to control the range of movement of the bar tov printing relation with the work on` the carriage to type a line on the work, means for moving the carriage, means for releasing the carriage to said moving means upon actuation of the type, a movable spacing bar arranged to be engaged with the carriage, means for moving said bar, clutch means on the bar for temporarily holding. it againstmovement, means controlled by the type actuating means and movable to active position, upon actuation of a type, to engage the spacing bar and limitI the range of the carriage movements, an electrically operable holder controlled by the type actuating means and effective to temporarily hold the carriage stationary while the range limiting means are moved to active position, means to thereafter engage the clutch to effect the subsequent, simultaneous movement, of the carriage and spacing bar, means arranged to be set by the line typing mechanism and under the control of the operator and means arranged to be actuated by said last mentioned means and effective, when actuated, to be automatically adjusted to control the range of movement of the spacing bar in accordance with the overrun of the typed line and the number of characters in the ne whereby the line will be justified when it is re-typed.

3. A typing machine comprising a frame, a work holding carriage movable on the frame, a plurality of printing type, means for selectively actuating the type into printing relation with the work on the carriage to type a line on the work, means for moving the carriage, means for releasing the carriage to said moving means upon actuation of the type, a movable spacing bar adapted to be clutched with the carriage, means for moving said bar, clutch means on the bar whereby the bar. may be clutched with the carriage, means controlled by the type actuating means and movable into active position, upon actuation of the type, to engage the spacing bar and to limitthe range of carriage movement, a holder controlled by the type actuating means and effective to temporarily hold the carriage stationary while the range limiting means are moved to active position, means to thereafter cause the engagement of the clutch to effect the subsequent simultaneous movement of the carriage and spacing bar, means arranged to be automatically operated to control the range of selectively actuating the type into printing rela-A tion with the work on the carriage, a movable dog connected to and actuated by each of the type actuating means, a movable spacing bar,
